Remarks:
The AT-1 is essentially an AE-1 without shutter speed-priority AE. It was produced
to satisfied some overseas markets where price is a main factor for consideration
for an SLR camera.

Further, for those who still preferred manual metering, the AT-1 there to serve.
It shares almost the same dimension as the AE-1. It has a match-needle metering and
TTL centerweighted averaging metering but with a less sensitive CdS photocell than
comparative bodies around its time. Accessories like Winders, Databack A and Speedlites
designed for the AE-1 can be used and shared.
